If you are attempting to walk through a maze, you will probably walk down a path as far as you can go. Eventually, you will reach your destination and exit the maze or you won\u2019t be able to go any farther. If you can\u2019t go any farther, you will need to consider alternative paths\u2014you will need to backtrack until you reach a fork and follow a branch you did not travel hoping to reach your destination. Backtracking is a systematic, nonrepetitive approach to trying alternative paths and eliminating them if they don\u2019t work.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
